Abstract: Curable fluororubber compositions exhibit excellent processability on roll mills and can be molded without sticking to or staining the mold surfaces when the composition contains from 0.1 to 30 weight parts per 100 weight parts of fluororubber of a finely divided cured silicone material in the form of a rubber, gel or resin. An epoxy-substituted alkoxysilane or a partial hydrolysis product thereof is present as an ingredient of the curable composition when it is desired to cohesively bond the cured fluororubber to a metal or plastic substrate.

Abstract: The cosmetic composition of the present invention exhibits excellent lubricancy since it contains silicone rubber powder containing 0.50-80 wt % of silicone oil. When it is coated on the skin, no foreign sensations or irritations are reported. A smooth and moist texture is obtained.

Abstract: A polymer binder, in which the content of a residual monomer is not more than 200 ppm, generates a smell only to a very slight extent and provides a toner having an improved blocking resistance and resistance against a plasticizer for polyvinyl chloride. The polymer binder is prepared by maintaining a polymer suspension obtained by suspension polymerization at a temperature of not lower than the glass transition temperature of the polymer and distilling water in an amount of 5 to 60% by weight based on the amount of water present at the time of termination of the polymerization.

Abstract: An image duplicating apparatus including an optical exposure lamp by which a document bearing images is to be scanned by illumination with light, a photosensitive drum on which the images on the document are to be reproduced, a slot through which the light reflected from the document is to be passed toward the drum, and an automatic exposure control system which detects the density of the images on the document from the intensity of the light passed through the slot. The automatic exposure control system produces a first signal representative of the detected image density and produces in response to the first signal a second signal indicative of whether or not the illumination value is adjustable in a real-time automatic exposure control mode.

Abstract: Cured silicone rubber powder containing large amounts of particulate material formed by dispersing a liquid silicone rubber composition curable by a platinum-catalyzed hydrosilation reaction into water. The presence of a low molecular weight, volatile polydiorganosiloxane makes it possible to incorporate at least 100 parts by weight of particulate material per 100 parts of curable polydiorganosiloxane into the composition. The volatile polydiorganosiloxane is removed from the cured polwder. Finely divided magnetic metals, electrically conductive materials and reinforcing silica powders can be incorporated using the present method.

Abstract: The curable resin composition of the present invention consists of a curable resin and the spherical microparticles of cured silicone rubber obtained by the curing of an addition reacting silicone rubber composition, wherein the silicone rubber composition also contains an epoxy compound having an aliphatically unsaturated group. Furthermore, because the microparticles are prepared from an aqueous emulsion or aqueous dispersion of the silicone rubber composition, it has an extremely small particle size.

Abstract: The present invention provides a method for producing silicone rubber moldings composed of a uniform, smooth and hard exterior layer and a relatively soft interior portion. In accordance with this method the surfaces of the mold cavity are coated with an organohydrogenpolysiloxane containing at least two silicon-bonded hydrogen atoms before the curable organosiloxane used to form the interior portion of the molding is injected into the mold cavity and cured.

Abstract: Cured silicone rubber in the form of a finely divided powder is prepared by (1) dispersing a heat-curable liquid silicone rubber composition in water maintained at a temperature of from 0.degree. to 25.degree. C., (2) dispersing the resultant dispersion in a liquid heated to a temperature of at least 50.degree. C., and (3) recovering the resultant cured powder. The liquid silicone rubber composition is preferably maintained at a temperature of from -60.degree. to 0.degree. C. before being emulsified and said liquid is preferably water.

Abstract: In an original illumination device with an automatic illumination control according to the present invention, light from an exposure lamp (6) illuminates an original (1) and a reference density plate provided on the lower surface of a table (2), reflected light from the original (1) is directed to a photosensitive drum (13), and reflected light from the original (1) and the reference density plate (3) is detected by a photo detector (14), whereby an MPU (17) controls power supply to the exposure lamp (6) by an exposure lamp regulator (19) based on the detection output of the photo detector (14).

Abstract: A copying apparatus equipped with an improved control device for controlling a copying operation, and including a device for generating a start signal for starting the copying operation, a paper feeding device for starting feeding of copy paper sheets in response to the starting of the copying operation. The control device comprises a device for generating a stop signal for stopping the copying operation and a device for preventing starting of operation of at least the paper feeding device when the stop signal is generated after the start signal has been generated and before the paper feeding device is operated.
